The Language Center administers placement tests to all students who intend to continue studying a foreign language at Stanford. The purpose of testing is diagnostic: it assesses students' current language abilities in order to match them to the course most suitable for that level. For more information, please see Placement Testing.
Most students who take first- and second-year (and some third-year) -LANG courses also have speaking and writing exit tests. The SOPI (Simulated Oral Proficiency Interview) and the WPA (Writing Proficiency Assessment) are designed to measure what students can do functionally with the language, and consist of real-life speaking and writing tasks.
For more information, see the Language Center's Exit Testing page.
